Barrier assessments for Bristol Water

The BART team have been busy this month doing barrier assessments for Bristol Water to understand which fish species (if any) can get over a number of weirs. Fish need to move along rivers to feed, breed and to find suitable habitat and unnatural features such as this prevent this, as well as detrimentally affecting the rivers habitats and flows. If you are interested, you can read more on the impacts of weirs here.

 

Bristol Avon WaterBlitz 2018 – the results

Our Bristol Avon WaterBlitz is run annually to assess the health of the rivers and the streams within the catchment. As part of the WaterBlitz, participants test the water quality by taking samples to find out the levels of nitrate and phosphate in their chosen river or stream.

This year’s Bristol Avon WaterBlitz was run between the 23rd-29th of June 2018. The event engaged with over 260 participants to take 120 samples within the Bristol Avon catchment.

The WaterBlitz uses these results to assess the levels of excess nutrients in the rivers/streams in the catchment. Nitrate and phosphate occur naturally in rivers and are nutrients for plants and essential for wildlife. Excessive amounts of these nutrients may cause toxic algal blooms which harms aquatic insects and fish by decreasing oxygen levels and increases the cost of treating drinking water.

This year’s results shows that there is an increase in phosphate from last year, with 0.1mg/l, with an average of 0.16mg/l which is slightly above the agreed levels for a healthy river. However, nitrate levels have decreased with an average of 3.1mg/l compared to last year’s 4.2mg/l. Nitrate has no official standard for levels in rivers/streams.

To see more results please see the Interactive Results Map here.

Thanks to the Bristol Avon Catchment Partnership for funding this project this year.

We are already on the lookout for funding to run this important research project again next year so if you are a business or individual who could help, do get in touch!

BART takes to the water at the Bristol Harbour Festival

Did you spot the BART logo in the Bristol Post, Telegraph or Sunday Times this weekend?

BART Project Manager Harriet took to the water in a cardboard boat this weekend for the ‘My Future My Choice‘ cardboard boat race at the Bristol Harbour Festival.

Her boat, HMS Fatberg, was created to raise awareness of the issues with fats and wastes being poured down our drains. You can read more about this issue here.

No win (more of a big sink!) but great to see the BART logo in the news!

Fish passage assessments at Radstock

Yesterday BART spent the day on the Wellow Brook assessing fish passage on three weirs in Radstock. We measured the physical characteristics of the weirs including water depths, height and length of structure and also flow velocities and inserted these into a database which calculates the passability of the structures for a number of different species. Unfortunately, the database confirmed that all three barriers presented a barrier to a range of fish species and therefore we will be investigating weir removal possibilities or fish passage options for these in the future.

This work is part of our wider Wellow and Cam Initiative which we have been working on for a number of years but which has picked up a lot of pace recently. The initiative includes: weir removals and fish passage surveys, coppicing, instream work, river corridor surveys, macroinvertebrate surveys, electrofishing surveys, land management advice , education and much more.

This piece of work was funded by Tesco Bags of Help – thanks to everyone who voted for us with your tokens in store!

 

Free GIS training opportunity for secondary schools

Calling all Secondary school teachers in the Bristol area!

Bristol Avon Rivers Trust are offering an exciting opportunity to become a member of a steering and development group for our new GIS Geography education project. Since the introduction of GIS to the curriculum, a lack of CPD opportunities for teachers to learn how to use it has become a barrier to its use in the classroom. BART will be developing this GIS project to provide an outstanding, locally focused and cross specification teaching package aimed at KS3-5 pupils and teachers.

GIS is an essential tool to many industries including urban planning, government, business and marketing. Its importance in everyday life is growing as human pressures on the environment increase with growing populations. As outdoor education and engagement with the natural environment is reduced with health and safety restrictions, GIS represents a crucial way for teachers to educate young people on the water cycle and land and river management, and we are in an exciting and privileged position to develop this opportunity.

We will be developing this GIS package through a teacher liaison panel to co-design the programmes of study. Contributing teachers can expect to benefit from this unrivalled CPD opportunity by becoming fully trained in using GIS and delivery of the programmes of study. This will enable you to return to your school as a GIS teacher specialist, allowing you to lead the delivery of GIS training and teaching in your own school. This is a free opportunity and travel expenses will be covered.

The project aims to teach competent transferable GIS skills whilst developing pupils understanding of some of the many locally important physical and human geographical features in the Avon catchment. Contributing teachers will need to be able to commit to attending a 3 after-school training sessions in Bristol.

If you are interested in being involved in the liaison panel, please get in touch at alec@bristolavonriverstrust.org
